An investment of 4,000 earns 2% interest compounded annually. What will be value of the investment in 7 years
Start with your exponetial growth formula: y = a(1 + r)^t.
Now, a is going to be your initial amount, r is the rate, and t is the time.
So we have y = $4,000(1 + .02)^7.
Now simplify inside the parenthses first.
So we have y = $4,000(1.02)^7.
Simplifying further gives us y = $4,000(1.14868).
Now use a calculator to get y = $4,594.72
The volume of the square pyramid is ___ cubic centimeters.
Answer:
The volume of the square pyramid is 1,125 cubic centimeters
Step-by-step explanation:
From the diagram in the question, we have;
The height of the pyramid, h = 8 cm
The side length of the square base of the pyramid = 15 cm
The area of the square base of the pyramid, A = 15 cm × 15 cm = 225 cm²
The volume of a pyramid = 1/3 × A × h
Where;
A = The base area of the pyramid
h = The height of the pyramid
Therefore, the volume of the square pyramid, V = 1/3 × A × h
∴ V = 1/3 × 225 cm² × 15 cm = 1,125 cm³
The volume of the square pyramid, V = 1,125 cm³
If 8 bottles of cold drink is Rs.480. Then find a) What will be the cost of 5 bottles of cold drink? B) How many bottles of cold drink can be purchased for Rs.640.
Answer:
(A) 300
(B) 11
Step-by-step explanation:
8 bottles of drink cost 480
Therefore one bottle will cost
= 480/8
= 60
(A) 5 bottles of cold drink will cost
= 60×5
= Rs300
(B) The bottles of drink that can be purchaseed at Rs640
= 640/60

A person's height is 5-ft 3-in. Their shadow has a length of 3-ft 6-in. If a nearby tree has a shadow of length 10-ft 4-in, what is the approximate height of the tree?
Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
[tex]\dfrac{\text{Height of tree}}{\text{Height of person}}=\dfrac{\text{Length person's shadow}}{\text{Length of tree's shadow}}\\\\\dfrac{\text{Height of tree}}{63}=\dfrac{124}{42}\\\\\Rightarrow\ \text{Height of tree}=\dfrac{124}{42}\times63=186\ inches\\\\=\dfrac{186}{12}= 15.5 ft\ or\ 15 ft.\ 6\ inches.[/tex]
Hence, the height of tree = 15 ft. 6 inches

Work out the size of angle x.
126°
43°
Answer:
the answer is 83°
Step-by-step explanation:
by the sum of iner and outer angle=180°
180-126= 54°
x=180-43+54
x=180-97
x=83°
The measure of angle x is 43°.
What is Triangle?
A triangle is a three sided polygon , which has three vertices.
Given that;
In triangle, The value of interior angles are 43° and x°.
And, An exterior angle is 126°.
Since, The sum of two interior angles is equal to the exterior angle of same triangle.
Hence, We can formulate;
43° + x = 126°
Subtract 43° both side;
43° + x - 43° = 126° - 43°
x = 83°
Thus, The measure of angle x is 43°.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.48 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
how much does the meal cost?
Answer:
Step-by-step explanation:
c=t+p
c=0.2(78.84)+(1-0.15)(78.84)
c=0.2(78.84)+0.85(78.84)
c=15.768+67.015
c=15.77+67.02
c=$82.79
Solve for x in the diagram below.
3x
100°
2
Answer:
20 degrees
Step-by-step explanation:
The line has a total of 180 degrees. So, x+100+3x=180. Then, we subtract 100 from both sides to get x+3x=80. Then, x+3x=4x. So, 4x=80 degrees, and so divide by 4 on both sides and you get x=20 degrees.

∠3 = 24°
∠4 = 90°
Step-by-step explanation:
∠1 = 90 - 24 = 66°
∠2 = 24°
∠3 = 24° because segment DB bisects ∠ABC
∠4 = 90° because it is a right angle
Three bags of chips and sodas cost $12.50. Four bags of chips and two sodas cost $10.00. What is the cost of each item? ASAP pls!
Step-by-step explanation:
3c + 3s = 12.50
4c + 2s = 10.00
3S = 12.50-3c
s = 4.17 - c
4c + 2 (4.17-c) = 10.00
2c + 8.34 = 10.00
2c = 1.66
chips = 0.83
soda = 3.34

Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet. It cost her $945 to fence in the yard. If fencing costs $15 per foot, what is the width of Claire's backyard?
Answer:
Step-by-step explanation:
You need to know the formula for the perimeter of a rectangle. We won't use it right away, but it is pertinent information.
P = 2 ( l + w )
Now, we know that the fencing costs $15.00 per foot, and that the length is 19.50 feet.
We first need to find the price of one "length" side of the fence.
To do this, multiply 19.50 by 15.00
19.50 x 15.00 = 292.5
Next, we look at the perimeter equation to see what we can plug in where.
P = 2 ( l + w )
We can put in the total price of the fencing for the yard as P, and the amount of one length side of the fence as l.
945.00 = 2 ( 292.5 + w )
And now, we simply solve for w.
945.00 ÷ 2 = ( 2 ( 292.5 + w ) ) ÷ 2
472.5 = 292.5 + w
472.5 - 292.5 = 292.5 + w - 292.5
w = 180
It costs $180 for one "width" side of the fence.
To find out how many feet that is, we do the opposite of what we did with the length. Instead of multiplying by $15.00, we divide by $15.00
$180.00 ÷ $15.00 = 12
The width of Claire's backyard is 12 feet.

12x8.5ft= 102 ft
7x18.5 ft= 129.5ft
24x 1.75ft= 42ft
12x 6.5ft=78 ft
2x 34.25= 68.5ft
Add all the answers and you get 419.5 ft
find the perimeter and area of rectangle JKLM. K(1,5) L(4,2) M(2,0) J(-1,3)
Answer:
perimeter: 10 units
area: 6 square units
Step-by-step explanation:
within the picture point J and point M seem to be 3 units are.
with this assumption, with can infer that both parallel sides are 3 units giving us 6 units for both sides
we can as well as tell that point J and point K seem to be 2 units apart.
with this info we can infer that both parallel sides will be the congruent lenght. which will add up to 4
thus giving us the equation for the area
6 + 4 = (10 units) for the perimeters
for that area we will then do 3 units by 2 units
(3 units for the assumed length and 2 units for the assumed width)
giving us the equation 3×2 = (6 square units)
